To al 11i/tom t may concer/n:

Be it known that l, Francisco CLARK, a citizen of Mexico, and resident of Durango City, Durango, Mexico, have invented a new and Improved CombinationLoclr, of which the following is a full, clear, and exact description.

This invention relates generally to a new and improved combination or permutation lock, and more particularly to a lock ot this character havinga plurality of tumbler members, actuated by a key to permit a .bolt or latch control member to be moved.

(lne of the objects of this invention is to provide a combination lock of simple and compact construction, in which a plurality or tumbler members adapted to be actuated by a lrey, are provided with a means of simple construction,which may be readily adjusted to determine the movement of tumblers to permit the movement of a bolt control member.

[i further object of' this invention is to provide in aV combination loclr a simple and compact construction which will permit a single lrey to be used which will properly position the tumbler members of the lock, which will in turn permit the key to turn a bolt control member of the lock.

ifi. further object ot this invention is to provide in a combination lock, having tumbler members one end of which is exposed in the lrey hole, a means which will permit cach ot the tumbler members to have the same limits of travel, whereby the possibility ot a. person determining the exact settino; or combination of the lock is prevented.

.d further object of this invention is to provide in a, combination lock having tum- `bler members, which normally restrain the movement oi a bolt control member, a simple and incr; Jensive means adjustable on 'he tumblers for determining the necessary movement thereoi'l in order to permit mover ment ot' the bolt control or actuating member. l

Still another object of this invention is to lprovide in a combination or permuta tion loclr, a construction which will permit the tumbler members thereof to be directly actuated axially of a bolt control member, by corresponding ward members, 0i a key and when moved a predetermined distance, will permit the bolt control member rotatably mounted, to be actuated.

Still a further object of this invention is to provide in a combination lock, a key construction having a body core portion, and a means rotatably mounted thereon for receiving` longitudinally adjustable ward members.

The above objects are accomplished, in the practical embodiment shown herein, by providing in a combination lock, a bolt or latch, connected by a suitable means to an independent bolt control member rotatably mounted, and a plurality ot spring pressed tumbler members movable axially of the control member and normally restraining the said member against rotary movement, a suitable means being provided to hold the said tumblers in proper relative position and against rotary movement, a means being provided for limiting the movement of each of the tumblers in eac-h direction. A means longitudinally adjustable of the tumblers is provided for determining the movement required oit the tumblers axially ot the bolt control member, in order to afford an annular open path which will permit rotary movement ot the bolt control member.

Other objects and advantages will be apparent trom the following description and the accompanying dra-wings, and the invention more particularly pointed out in the appended claims.

Similar characters ot reference designate corresponding parts in the several views. In the drawings showing one ot the practical embodiments ofk the invention,

Fig. il is an end view oi' that portion oi the lrey body which engages the bolt actuating member of the lock.

ln the drawings showing,- one practical embodiment of the invention, a bolt control member l rotatably mounted, is preferably cylindrical in torni, and is provided with a toothed or notched collar 2 extending circumferentially around the same. Slots 3 are formed by the tooth-like projections 2, the n`function otwhich will later appear. Y il bolt 4 which may be of any suitable form, is mountedin a suitable casing` 5 to move transversely ci the bolt control member l. Any suitable means may be provided between the bolt control member and bolt, tor effecting movement thereof. ln the form shown, tor example, a pinion mounted Von the bolt control member l, engages a toothed rack portion l et the bolt. lt is thus seen that the bolt may be moved by turning the bolt control member l in the desired direction. Further, it is to be noted that if the bolt control member l is locked or held against movement, the bolt i will also be locked or held against movement. ln the form shown, a recess 8 is arranged in one end ofthe bolt control member, and is adapted to receive a correspondingly shaped portion 9 extending` from a key body l0, so that when the key is turned, the bolt will be movedby the control memberl. lt is to be understood however that any suitable means may be provided between the lrey and the control member for effecting turning movement thereof. Preferably, the end 8 of the control member will extend in a lrey hole 11 Jformed by the esoutcheon plate 1&2-, shown secured by screws 13 to a door lll shown in dotted outline. lt is understood however that the lock may have other ap' ilications than to a door.

A s a means ot' normally restrainingthe said bolt controlling` member l against rotary movement, tumbler members l5 are ranged about the said control member, and are movable axially thereof, each ot said tumbler members being provided with Ya, means adjustable thereon jor determining vthe movement oi the tumbler members arrially of the control member l, in order to permit rotary movement of the `control member. ln the form shown, the said adjustable means comprises a plurality oi pins l5 which are seated in openings 17 Vspaced in the Vtumbler's l5. A tubular casing` 18 is provided to incase or lit around the tumbler members 15 arranged about the bolt actuatythe lock, are

' are provided, one end 26 of each Ylinger sing Any suitable arrangement may be provid sinon, as will correspond Vas ior instance the end mns,

ingr member i, the said casino" serving to hold the tumblers in proper relative position. A stop or webA 19 entends inwardly from the casing 18, between certain ot the tumblers, order to prevent relative rotary movement between the casing 18 and the Y tumblers l5. @ne end of the casing extends to the escutcheon plate l2, a shoulder 2O being provided at the other end, which serves as a stop to limit the movement in one direc- 7e tion ot all the tumblers held in proper position, it being,` only ecessary in order to disconnect the tube trom the plate to turn the screws ytlnough halt a revolution. rlhe tumbler members and other parts of .Se

preerably so proportioned that one end 2li o'l" the tumblers will normally be positioned in the lrey hole ll, the oit the tumblers, the escutcheon plate l2 and the exposed end oi the plate or control member l, preferably ein@` in abn-ement to form a substantially smooth su. ic ils a means ot normally holding the tumblers i5 in a iorward position, the sprino` lingers 2 connected to the plate 22 by a screw or other suitable means, the other end 27 normally engaging a tumbler member, so as to exert a spring pressure on same at all times.

for eitlecting,` a spring` pressure upon t e tumblers, but preferably the flat bent spring linger is provided, such a construction beiup,` particularly adapted tor use herein on account ol' the convenient and compact con struction, because the arrangement is such that a spri pressu'e is afforded throughut the limits of movement oic the tumbler. As means ot l' iting` the movement oi' each oi the tumble members inward ot the 'l loch, the iaceioo of the casing' is arranged such distance n he members when occupying th" movement desired of the tuin the `tumblers l5 are moved bolt control Vmember l, the pins, moved through the slots 3 `lormed projecting tooth portions 2. li instead of hav-ino the rea yard movement oit the tumblers ited the tace c8, the said rear wird moi ment may be limited thev teeth 2, engagi 'the sh ulder ot d f tumblers. 'lv/Jhon the tumblers or upy th normal forward position, ich posit will be assumed when the hey is not in tha lrey hole, cerain of the adir tab Ypins lll, e witlrn tooth a slot 3 betriee the tions 2, and will thus prevA ment or the bolt control mem prevent movement oiC the bolt the pins, onv each ot the tumblers, erablytwo as shown, which will correspond to thewidth of the tooth portions 2, are

Cit

removed, so that When each oi the tumblers have been moved such a distance as will bring the opening thus formed in alinement with the toothed portions 2 on the bolt control member l, open pathway 30 will be formed, Whioh will permit the tooth portions 2 to pass therethrough7 thus permit ing relative rotary movement between the tumblers l5, and the bolt Control member l, which movement Will in turn permit the bolt d to be actuated. it is to be understood that any suitable arrangement and construction of the tumblers and adjustable means for determining the movement thereon and the bolt control member and projecting,n tooth portions may be provided7V this invention not beinelimited to the form shown herein. ln a look of this character, in which one d oi the tumbler members are exposed in the liey hole, it is particularly desirable to have a means which provides for the same limit oi" movement for each of the tumbler inembers in order to prevent unauthorized persons from tampering 'thereivitlnv and to prevent their determining the exact setting` oli the adjustable means on the tumblera spondingto a similar settingI oithe Wards 3l of the lrey, which represents the combination oi the particular loclr. i however, it is desirable to change the combination oi' the loclr9 it is only necessary to change the position oi the pins lo ot the tumblers, and to maire the corresponding change in the setting` of `the Wards or the hey. Any suitable number or tumblers may be employed in the lock, and any suitable number oi adjustable pins may be provided7A depending` upon the particular number ot combinations or separate settings it is desired have `for any given lock. ln the form shown, employing l0 tumbler members, and 5 adjustable pins, the mechanism of tl e loolz may be set for over a million combinations.

lln the iorm shown7 lrey is provided having a key body 9, including a Cylindrical core l0, and a. handle 82 oonneoted thereto, the construction being such that the Ward embers 3l arranged about the core in a position eorrespondi to that of the tumbler members l5 of the lock, the eens ruction being' suoli that the ooi-ie i0 oi the lrey may be rotated relative to the Wares.. and a means being' also provided to permit adjustment of the Wards 3l longitudinally oit the lrey. The purpose oi' such an arrangement is to permit the Ward members 3l of the lrey to move the corresponding' tumbler members l5 of the loolr suoh a dis will form an open pathway to per i movement oit the bolt control member l. which movement is eifected by turning' the handle oi the hey. lt is thus seenthat the core l() oi' the lrey and the bolt control member l oi" the loolr, may be rotated relative to the Wards 31 and tumblers l5 of the key and tanee '4. it

loelr respectively. in the key shown, a cy lindrical casing 33 is provided which his over the core lO of the lrey body and is held against longitudinal movement thereon, by a suitable means beim;- provided to prevent movement oi the casingl 33 longitudinally oi' the lrey body, but permitting relative rotary movement between the said core and the casing. For this purpose, a groove Sli extends circumierent'elly about the core l0, and a serevv or other suitable means er:- tends through the casing, the end 36 olf the screw extending Within the groove or slot Si. in annular opening` 8? extends invvarfjl irom the end oi' the casing, in Whieh opening the Ward members are arranged, so as to pen mitV movement tor adjustment longitudlnally thereon Any suitable means may be provided for this purpose, but in the iorm shown, the Wards are provided with spaced slots 38 preferably Corresponding in number and arrangement 'to that oi' the adjust able pins 16 for the tumblers. a means of holding` the said Wards in adjusted position, spring lingers S9 are provided, pret erably one for each or the Wards, each ot the lingers havingv a bent end portion 4l() adapted to lit `fvithin the slots 38 of the wards, preferably in such manner as to hold the Wards against movement in either direction. ln order to readily adjust the setting of the Wards, openings el are formed between adjacent spring fingers 39 so that the end of a pointed instrument e2, such as a pin, may be inserted Within the opening so that the spring' linger 39 may be conveniently and readily raised to disengage the bent end portion el() from the slot 38. rIClie springl fingers 29 may be arranged iu any suitable manner about the easing 33a but preferably the outer surface olf the easing` is ilattened, to accommodate the spring; lingers, and the said iingers are preferably formed from one piece ot material, and held in proper position by the sorevv 35. is a means oi holdingl the Wards 3l in proper relative position to the casino; 33% a Web portion integral or tinted to the casingI extends between certain el the Wards. ln order to facilitate proper positioninov oi the members oi the liey with respect to the Correspending` tumbler members oi the locln the web portion 3 of thelrey may project a certain distance and iit Within a. recess of the loclr Corresponding to the position oi the web portion 19.

While one practical embodiment of the in-V vention has been shown and described here in, it is understood that various changes and modifications may be kmade Without departino; from the spirit and scope of this inwen-` tion.
